Choo Soo-ji

Choo Soo-ji was a Goguryeo officer who served as Yang Manchun's right-hand man during the Goguryeo-Tang War. He helped his general defend their hometown during the Siege of Ansi, and, while he did not initially trust Eulbul Sa-mul, he ultimately came to respect him after he assisted in the defense of the city. After 80 days, the Koreans managed to defeat the Chinese army by using several ploys, successfully defending Korea from invasion.
